Abstract
The utility model relates to a kind of camshaft lubrication oil channel structures, belong to the technical field of engine fittings fabrication design, described oil channel structures comprises camshaft axis body and is arranged on the many groups valve cam on axis body, often organize between valve cam and be provided with camshaft bearing journal, and on the outer circle wall of camshaft bearing journal, there is oil groove.Compared with prior art, the utility model by arranging oil groove on camshaft bearing journal, not only reduce difficulty of processing, ensure that the uniformity that each axle journal lubricates and lubrication effect, and surface friction drag and the wearing and tearing of motor camshaft when cold start-up can be avoided.
Description
Technical field
The utility model relates to the technical field of engine fittings fabrication design, and more particularly, the utility model relates to a kind of camshaft lubrication oil channel structures for motor car engine.
Background technique
In the lubrication system of motor car engine, the parts of lubricating oil in main oil gallery leads to camshaft bearing, cam, timing chain through undue oil circuit, then returns oil sump by oil circuit.For this reason, structure conventional in prior art is machining hole or oil circuit on camshaft bearing journal, but camshaft axial wall is very thick, and in the middle of camshaft, oil circuit hole machined is too dark, and not only processing cost is high, and difficulty of processing is also large especially; Trapped fuel in addition in oil circuit hole is not good to the lubrication of camshaft when engine cold-start, and surface friction drag can be caused to increase and camshaft inordinate wear.
Model utility content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of camshaft lubrication oil channel structures.
To achieve these goals, the utility model have employed following technological scheme:
A kind of camshaft lubrication oil channel structures, comprises camshaft axis body and is arranged on the many groups valve cam on axis body, it is characterized in that: often organize between valve cam and be provided with camshaft bearing journal, and have oil groove on the outer circle wall of camshaft bearing journal.
Wherein, described oil groove is circular, and the Normal direction of described oil groove place plane is the axial direction of camshaft.
Wherein, described axis body is provided with organizes valve cam more.
Compared with prior art, camshaft lubrication oil channel structures described in the utility model has following beneficial effect:
Different from the lubrication strategies processing oilhole in prior art in the middle of camshaft, by arranging oil groove on camshaft bearing journal, not only reduce difficulty of processing, ensure that the uniformity that each axle journal lubricates and lubrication effect, and surface friction drag and the wearing and tearing of motor camshaft when cold start-up can be avoided.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the camshaft lubrication oil channel structures of embodiment 1.
Embodiment
Be further elaborated camshaft lubrication oil channel structures described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
As shown in Figure 1, camshaft lubrication oil channel structures described in the present embodiment, comprise camshaft axis body 10 and be arranged on 3 groups of valve cams 20 on axis body, often organize between valve cam 20 and be provided with camshaft bearing journal 30, and on the outer circle wall of camshaft bearing journal, there is oil groove 40.Described oil groove is circular, and the Normal direction of described oil groove place plane is the axial direction of camshaft.The utility model, by processing and lubrication oil groove on camshaft bearing journal, eliminates the design proposal of middle oilhole; Oil from each Cam bearing pedestal of cylinder head during lubrication, through each axle journal of camshaft lubrication Sump lubrication; And the oil groove on described axle journal can be obtained by the form of casting or processing, mode of execution is flexible, the low and high lubricating effect of cost.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
Claims (3)
1. a camshaft lubrication oil channel structures, comprises camshaft axis body and is arranged on the many groups valve cam on axis body, it is characterized in that: often organize between valve cam and be provided with camshaft bearing journal, and have oil groove on the outer circle wall of camshaft bearing journal.
2. camshaft lubrication oil channel structures according to claim 1, is characterized in that: described oil groove is for circular, and the Normal direction of described oil groove place plane is the axial direction of camshaft.
3. camshaft lubrication oil channel structures according to claim 1, is characterized in that: described axis body is provided with and organizes valve cam more.
